To all whom it may concern Be it known that we, WILLIAM S. Pnonn ma, lVILLIAM H. Enwsnns, and ALEXANDER 1F. WINTnns, all citizens of theUnited Sta tes, residing at Grand Rapids, in the countyof Kent and State0t Michigan, have invent ed new and useful improvements in Loose- LeafBinders, of which the following is a specification.

The present invention relates to loose-leaf binders; and its object isgenerally, to provide such a binder which shall be simple and economicalin construction; and more particularly, such a binder having simple andreadily-operable adjusting means.

These objects are attained by, and the invention finds preferableembodiment in, the structure hereinafter described and illustrated inthe accompanying drawings, in which:

Figure 1 is a plan view of the inside of a loose-lent binder opened outfiat:

2 is a fragmentary view in perspective of the same:

Fig. 3 is a sectional view of certain parts on line 3-3 oat Fig. 1:

Fig, 4- is a like view of certain parts on line llof Fig. 1, and

Fig. 5 is a like view of the roughened sur- :lace 0t one cover, adaptingit to secure the leat-holding member against sliding or slackeningmovement.

in the embodiment of the invention chosen for illustration by thedrawings and lor detailed description herein, the covers 1 and Q areconnected by a flexible back 8. Flexible leaf-holding members ii: aresecured to one cover 1, as by being riveted between. anehor plates 5 tosaid cover. These leaf holding members extend through suitable slots ororifices of common form (not shown) in the binding edges of the leaves6,

and are slidable on the other cover 2 to adjust the covers to differentthicknesses of their contents. Each 0t" these leaf-holding members isthus slidably guided at its edges in a suitable guide 7 on cover 2, andpasses under an arm 8 pivoted at 9 on said cover and adapted to be swungin a direction parallel to the side or inner face of said cover andunder a keeper 10 positioned at that side oi said member opposite to thepivot 9. When swung into this position, the arm presses said member downagainst the cover and clamps or holds it in the adjusted post tion towhich it has been drawn. When the arm is swung to its other position(shown in Fig. 2) the said member is released and may be readjusted asdesired. The arm is secured against accidental disengagement from itskeeper by their suitable mutually-engaging portions 11 and 1%respectively, particularly shown in Fig. 3. The arm, being preferably ofspring material, is readily sprung to disengage the said portions 11 and12, and being released from the keeper, springs away from theleafholding member and cover 2, thus permitting the ready adjustment oisaid member? and owing to such spring character and to the positioningof the keeper and the arms pivot on the opposite sides of theleaf-holding member, the arm in its holding position spring-presses saidmember between it and said cover.

A stop 13 on cover 2, limits the arm in its releasing movement fromswinging beyond the position of the leaf-holding member as the same isconfined edgewise in the guide: thus, said member guided and heldagainst edgewise movement by the guide 7 and by the swinging arm againstsuch fiatwise movement as would take it out ofsaid guide.

Cover 2 has a roughened surface 14 immediately under the leafiholdingmember, which is adapted to more securely hold, in the arms operative orholding position, said member against sliding movement: and suchroughened surface is preferably formed as shown in Fig. 5, wherein theprojections or teeth slope toward the binding edge of the cover and areabrupt toward its opposite edge, thus more securely holding said memberagainst that movement which loosens or slackens it.

The invention being intended to be defined solely by the claims, is notto be limited by details of construction shown or described.

hat is claimed is:

1. ln a loose-leaf binder; a pair of covers, the second of which has aguide for the edges of the leaf-holding member hereinafter named; aflexible leafiholding member secured to the first cover; and an armpivotally mounted on, and adapted to be swung in a direction parallelwith the side of, the second cover, to one position in which it holdsagainst movement said member beleases said member;

tween the arm and second cover and to another position in which saidmember is released; the second cover having a stop adapted to limit thearm in its said releasing movement from swinging beyond the position ofsaid member as guided in said guide.

2. In a loose-leaf binder; a pair of covers, the second of which has vakeeper and also a guide for the edges of the leaf-holding memberhereinafter named; a flexible leaf-holding member secured to the firstcover; and an arm pivotally mounted on and adapted to be swungin adirection parallel with the side of, the second cover, to one positionin which it engages the keeper and clamps said member between the armand second cover and to another position in which it is released fromthe keeper and rethe second cover having a stop. adapted to limit thearm in its said releasing movement from swinging beyond the position ofsaid member as guided in said guide.

3. In a loose-leaf binder; a pair of covers, the second of Which has akeeper; a flexible leaf-holding member secured to the first cover and anarm pivotally mounted on, and adapted to be swung in a directionparallel with the side of, the second cover to one position in which itengages the keeper and clamps said member between the arm and secondcover and to another position in which it is released from the keeperand releases said member; the keeper being positioned on the secondcover on the opposite side of said member from the pivotal mounting ofthe arm; the keeper and arm having respectively mutually-engagingportions Copies ofthis patent may be obtained for five cents each,

adapted to hold the arm against accidental disengagement from thekeeper.

4. In a loose-leaf binder; a pair o'l covers; a flexible leaf-holdingmen'iber secured to the first cover; and an arm oi spring material andpivotally mounted on, and adapted to be swung in a direction parallelwith the side of, the second cover, to one position in which it holdsagainst movement said member between the arm and second cover and toanother position in which said member is released; the second cover haring a roughened portion under said member and adapted to secure it inthe arms holding position of said member against sliding morenn nl.

5. In a loosc-leaii' binder; a pair oi? covers: a flexible leaf-holdingmember serurcd to the first cover; and an arm oi spring material andpivotally mounted on, and adapted to be swung in a direction parallelwith the side of, the second cover. to one position in which it holdsagainst movement said member between the arm and second corer and toanother position in which said member is released; the second coverhaving); a roughenral portion under said member and adapted to secure itin the arms holding position of said member against sliding movement inthat direction which slackens oil said member.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
